Conclusion:

^ (?!. * 123.123.123.10). * $
Or C:

Textbox2.text = RegEx. Replace (textbox1.text, @ "\ n. * 123 \. 123 \. 123 \. 10. * \ n", "\ n \ r \ n ");
String result = RegEx. Replace (STR, @ "^ .*? 123 \. 123 \. 123 \. 10. * $ "," ", regexoptions. multiline );
RegEx Reg = new RegEx (@"(? <= ^ | \ R \ n )(?! 123 \. 123 \. 123 \. 10). + ");

Summary:

The expression that matches non-"non-content" rows should be written as: ^ (?!. * Non-content). * $

Find the rows in the preceding row, not ending with "200 0 64", and then delete

^ (?!. * 200 0 64). * $

I have been doing this test:
^ (?!. * 200 0 64) $
No. * I don't think there is any content in the back, so I don't want to write it. * if I don't want to write it, I just need to write it. Which of the following experts can give me some advice.
